JACOB SHAVOR, OF TROY, NEW YORK.

EMPPLOVEMENT IN STOVES.

To all whom it may concern:

Be it known that I, JACOB SHAVOR, of the city of Troy, county ofRensselaer, State of New York, have invented new and useful improvementsupon the Stanley Goal-Burner, patented January 4,1845, and extended orrenewed for a term of seven years from and after the 4th day of January,1859; and I do hereby declare the following to be a full, clear, andexact description of the construction and operation of the same,reference being hereby had to the accompanying drawings, and to theletters of reference marked thereon, and making a part of thisspecification.

Like letters represent and refer to like parts.

Figure 1 is a front elevation of the wellknown Stanley vcoal-burner,patented as aforesaid. Fig. 2 is a section showing the plate b, Fig. 3,and attached thereto the cone-grateor conicalring A, the partition-plateS, the boltholes D, the air-passage E, the tube B, and the apertures t't', through which air is admitted to the tire-chamber. Fig. 3 is avertical section perpendicular through the center of the lower section,cone-grate, &c., from frontto rear thereof, and fully showing myimprovements and the nature thereof, as hereinafter described and setforth. Fig. 4 shows the bottom plate, d, and the air passage or tube Ethrough the same and the flues around it. Fig. 5 shows the top plate, o,oi the base, the fire-cylinder h, the .brick C, the fire-grate G, thebolt holes for the rods D, the air passage or tube E, and the plate g,whereby the said tube is constructed in connection and in combinationwith the cylinder h. Fig. 6 is a transverse section through thecorner-fines, fire-cylinder, and fire-brick of thelower section of thesaid Stanley coal-burner, which parts are fully described in the saidLetters Patent thereon. It also shows the air passage or tube E and thecurved plate g, fire-cylinder h, and the bolts or rods D.

The nature of my improvements consists in the construction of a tube forthe purpose of conducting air up the back of the iire-cylinder, andimmediately between the back corneriiucs of the said coal-burner, to thetire-cham ber within said fire-cylinder and over the fire thereinthrough the said cone-grate thereof,

which said tube is constructed in the manner as and by the combinationhereinafter dcscribed and set forth.

It also consists in the mode or method of securing the upper and lowersections of the said Stanley coal-burner by the means hereinafterdescribed, so that the members of the lower section and the members ofthe intermediate chamber thereof will each and all be` firmly heldtogether, while the top section is removed from the lower section atpleasure, and each section retains its proper members, withoutinterference with each other, during the operations of cleaning andrepairing the dues, cone-grate, intermediate chamber, ,and cornice ofthe said coal-burner, or for the purpose of repairing any other part ofsaid coalburner when desired. l

Having thus set forth the nature and object of my improvements, I willnow give the construction thereof', to enable others to construct anduse the same, which is as follows, to wit: I construct the airtube Eupon the back of the recylinder h, by the use and combina tion of thecircular plate g therewith, which, when done, forms an air-passagebetween said .plate and said fire-cylinder. This air-tube extends fromthe lower part of the cone-grate or conical ring A downward inconnection with said fire-cylinder h, until it reaches the bottomthereof; thence a part of the said re cylinder is continued downwardthrough the base I, and through the bottom plate, d, Fig. 3. The saidcurved plate g is also continued downward, in combination with saidextended portion of the said lire-cylinder, until it reaches the bottomof the said plate d. There is a circular chamber, B, cast with and uponthe said cone-grate A. This chamber is made to exactly correspond to theshape and to unite with'the said air-tube 'E at the top or upper endthereof. This tube is for the purpose of conducting cold air from theunder side of the said coal-burner upward along the outside surface ofthe said fire-cylinder, whereby the said air becomes highly heated inits said passage upward, lafter which it is admitted to the iirechamberthrough the said cone-grate, to facilitate the consumption of theproducts of combustion therein. The air-passages through the saidcone-grate are shownat it', and may be one or more in number.

D D, Fig. 3, are' rods connecting the plates c and b to the oppositeends of the fire-cylinder h, thereby holding the same and all partsconnected therewith together by means of a head or nut and screw at thelower end thereof, and a nut and screw, c, at the upper end thereof.These rods continue upward, one at each corner of the said intermediatechamber, and through said chamber and through the plate a, which saidplate is the lower plate of the said upper section. The two sections arethen bolted and held rml y together by means of the nuts and screws j'upon the upper ends ,of the said rods. Vhen t-hese nuts f are removed,the said nuts e hold the lower section together, which allows the twosections to be discontinued from each other without any member ormembers of the same becoming disarranged, which is very desirable inmounting' said coal-burncrs-more soin cleaning and repairing the same,by which great expense in time and trouble in cleaning,` and repairingsaid burners is saved. rlhese two improvements constitute valuable andimportant fea' tures'in the said Stanley coal-burner, which make thesame more useful to the public.

Having thus described my improvements, what I claim, and desire tosecure by Letters Patent, is-

l. The combination of the air-tube E, the chamber `B in the conical ringor grate A, communicating with the tire-chamber by means of theapertures i, and the triangular lines, the whole being arranged andcombined in the manner substantially as herein described'and set forth.

2. The method of securing the said` upper and lower sections by means ofthe rods D D D D, with the nuts e e e e, and upper nuts, f f ff, thereonarranged, substantially as herein described and set forth.

In testimony whereof I have, on this 24th day ot' April, 1862, hereuntoset my hand.

JACOB SHAVOR.
